Pale blue crystals were obtained from an aqueous solution containing equimolar amounts of (dmpda)Pt(N-nic)2 (dmpda = 2,2-dimethyl-1,3-propanediamine, nic = nicotinate) and copper(II) nitrate and subjected to X-ray crystallography, which revealed that the crystals are a composite material of the formula [(dmpda)Pt(N-nic)2]2·Cu(OH2)5·2NO3·4.5H2O. Copper(II) nitrate was found to be intercalated between the platinum complex layers which were constructed by non-covalent bonding interactions such as hydrogen bonding, π-π* stacking and electrostatic interactions of the platinum(II) complex. A linear array of the intercalated cationic Cu(OH2)5 complex was observed. The value of the effective magnetic moment of the composite material is subnormal (μ(eff) = 1.57 BM) at room temperature.
